Abstract
Provided is a polarization splitting device. The polarization splitting device includes a first optical element. The first optical element comprises a light incident surface, a polarization splitting interface and a reflective interface, and the polarization splitting interface and the reflective interface are correspondingly arranged. Incident light enters the first optical element through the light incident surface, and is split into first light and second light through the polarization splitting interface; the first light is incident on the reflective interface after being reflected by the polarization splitting interface, and exits from the first optical element after being reflected by the reflective interface; and the second light exits from the first optical element after being transmitted through the polarization splitting interface.
